Hi there! The formula for compound interest is P(1 + r)^t, where P = Principal (initial amount), r = rate (percentage rate), and t = time (years). Let's start off by adding 1 to the percentage rate in decimal form. 1.5% is 0.015 in decimal form. 1 + 0.015 is 1.015. The amount of time is 2 years, so we raise that decimal to the 2nd power. 1.015^2 is 1.030225. Do not delete this decimal from the calculator. Now, let's multiply it by the principal, which is 12,000 British pounds. When you multiply that decimal by 12,000, you get 12,362.70. There. Mary's investment will be a value of £12,362.70.

bulgar [2K]

Answer:

The distance to his office is 2.5 miles.

Step-by-step explanation:

Given : Wade bicycles at a speed of 10 miles an hour and arrives at his office in only 15 minutes.

To find : What is the distance in miles to his office?

Solution :

The relationship between distance, speed and time is

\text{Distnace}=\text{Speed}\times \text{Time}

The speed of bicycle is 10 miles per hour.

Time taken is 15 minutes.

Converting into hours,

1 hour = 60 minutes

1 minute = \frac{1}{60} hours

15 minute = \frac{15}{60} hours

15 minute = 0.25 hours

Substitute the value sin the formula,

\text{Distnace}=10\times0.25

\text{Distnace}=2.5

Therefore, The distance to his office is 2.5 miles.

Alex777 [14]

Answer

14/15 kg

Step-by-step explanation:

Rewriting our equation with parts separated

=1+215−15

Solving the fraction parts

2/15−15=?

Find the LCD of 2/15 and 1/5 and rewrite to solve with the equivalent fractions.

LCD = 15

2/15−3/15=−1/15

Combining the whole and fraction parts

1−1/15=14/15

Solution by Formulas

converting mixed numbers to fractions, our initial equation becomes,

17/15−15

Applying the fractions formula for subtraction,

=(17×5)−(1×15)15×5

=85−15/75

=70/75

Simplifying 70/75, the answer is

=14/15

What are the coordinates of point S? On a coordinate plane, point S is 0.75 units to the left and 0.5 units up. (Negative three-
ZanzabumX [31]

Answer:

The coordinates of S is ( \frac{-3}{4}, \frac{1}{2})

Step-by-step explanation:

We are supposed to find the coordinates of point S

Point S is 0.75 units to the left

So, x coordinate of point S = -0.75 = \frac{-3}{4}

Now we are given that point S is 0.5 units up.

So, y coordinate of point S = 0.5 = \frac{1}{2}

So, The coordinates of S is ( \frac{-3}{4}, \frac{1}{2})

So, Option A is true .
